Plant light question

I need to replace bulbs. I have a question. Some of my bulbs are 6000K and some are 10,000 What is the difference? I need something the plants will like but not too bright as my keyholes don't like too much light
 
6000k has a redder spectrum and is better for plants strangely it doesn't appear as bright as 1000k which is very white and bright but the spectrum isn't as good for plants. Sounds like 6000k woeyld be better for what you need.

+1 on Dan's comments. I like the 6500k bulbs on my tanks. I find the 10,000k lamps to be too harsh.

The Kelvin (K) rating has nothing to do with the brightness of the light, it has to do with the color.

Plants like a K rating of around 6500. Usually I do planted tanks with one 6500 and one 10000 K light (I've got 2 for sale right now if they fit your fixture).

6500 encompasses more of the red-end of the color spectrum and I believe 10,000 encompasses the full spectrum and looks whiter.

Combining the two will bring out color in your fish and help keep your plants healthy. If your plants are healthy, they'll shade the tank, and your fish will be happy.
